the casting ring is an open-ring-shaped part with a hollow interior, a lower casting long hole communicated with the hollow inner cavity is formed in the upper side ring wall of the casting ring, and the distance between the two ends of the lower casting long hole and the opening end of the casting ring is equal; inner pouring pipes communicated with the hollow inner cavity are uniformly distributed on the inner annular surface of the pouring ring, each inner pouring pipe is of a sheet structure vertically extending towards the axis of the pouring ring, and an inner pouring gate is arranged at the tail end part of each inner pouring pipe;
the upper end of a vertical pouring tube in the pouring tube is connected with the pouring hole of the pouring basin, and an upper pouring long hole at the tail end of a horizontal pouring tube in the pouring tube is connected with a lower pouring long hole of the pouring ring.
And a foamed ceramic filter screen is arranged at the joint of the upper pouring long hole at the tail end of the horizontal pouring pipe in the pouring pipe and the lower pouring long hole of the pouring ring.
The pouring pipe is made of ceramic materials, the pouring basin and the pouring ring are made of resin sand, and the working surfaces of the pouring basin and the pouring ring are coated with refractory coatings to prevent sand washing.
The communication area of the settling zone and the bottom of the pouring zone in the inner cavity of the pouring basin is larger than the hole section of the pouring hole, so that the molten steel on one side of the pouring zone in the inner cavity of the pouring basin is higher than the flow gap at the lower part of the slag blocking plate.
Advantageous effects
According to the pouring system, the deslagging effect is realized through the pouring basin with the slag blocking plate and the filter screen, slag inclusions entering molten steel are effectively filtered, the purity of the molten steel entering the cavity is improved, and the flow direction of the molten steel entering a casting is effectively controlled. According to the pouring system, the inner pouring pipe is designed on the side face of the casting and is of a vertical slice type, the modulus of the inner pouring gate can be effectively reduced, cracks of the inner pouring gate are prevented, impact of molten steel on a casting mold in the mold filling process is reduced, meanwhile, the vertical inner pouring pipe is the same as the direction of a falling sand casting, and the problem of meat deficiency in the falling sand casting process can be effectively avoided.
